The email address already exists in this organization

Small Business Server 2003
Recently migrated to new hardware.

We have a public folder called 'SalesStuff' that is mail enabled.  It has several email addresses for our various domains.  It used to have "sales@domain.com" for an email addreses but it is no longer there.  When I try to add it, I get "The email address already exists in this organization".  What's more, the default email addresses, "salesstuff@domain.com" are now "salesstuff2@domain.com" and when I try to change the email address by removing the '2', I get that same error.

I've searched for the email address "sales@domain.com" through a couple of methods.  A query within Active Directory and also a query of the Recipients in Exchange System Manager.  The query results tell me that the email address "sales@domain.com" is assigned to the public folder "salesstuff".

The problem is, of course, that the queries tell me it's assigned to the public folder but it's not listed in the properties of that public folder as an email address and won't let me add it.

Ideas?

THANK YOU!!

Here's what I've tried so far to locate the email address owner:

Option 1:
Start the Exchange System Manager.
Click to expand the Recipients container.
Right-click All Address Lists, point to New, and then click Address List.
Click the Filter Rules button and verify that it is set to Exchange Recipients (the default setting).
Click the Advanced tab, click Field, and then click User.
Click E-mail Address.
In the Condition box, click Starts with, and then in the empty box to the right, type the first few letters of the address that you want to search for.
Check the lower window for matches.

Option 2:
Start Active Directory Users and Computers Microsoft Management Console (MMC).
Right-click the root-level domain, and then click Find.
In the Find box, click Custom Search, click user in the Field box, and then click Proxy Addresses.
Enter a condition and a value to search for, for example, starts with and SMTP:user@.
Click Find Now.

Both yielded the 'SalesStuff' public folder, but when I view the properties, the email address is not associated w/ it.

I've removed the public folder "salesstuff" and then stopped/started MS Exchange Information Store.  No help.

Run this in a command prompt, then open the addresses.txt file to see where the address is coming from:
dsquery * forestroot -scope subtree -filter "(&(mail=*)(proxyaddresses=smtp:*))" -attr sAMAccountName distinguishedname objectCategory proxyaddresses >addresses.txt

Open in new window

Thanks for the quick response.

The output is the public folder "SalesStuff".  But when I go to the properties of that folder, the email address 'sales...' is not shown.

So if you go to Exchange System Manager, go to Administrative Groups/first administrative group/servers/<servername>/first storage group/plublic folder store/public folders, right click on the public folder, go to the Email Addresses tab, you don't see that listed?
How long has it been since you removed the address?

Daniel: Correct.  To my knowledge it might now have even made the transition when we migrated to new hardware.

flyingsky: I was considerring mail-disabling all  the public folders and just starting over as there aren't too many that require email addresses...  I'm reviewing that option now.

Note: upon further investigation, something definitely went haywire w/ the migration as all public folders are mail enabled and most of them have incorrect email addresses now.  Example: projects@domain.com is now showing as projects2@domain.com.  When I try to change it back by removing the '2', I get the "The email address already exists in this organization" error.

...followed the link instructions and removed the folder from ADUC.

From within System Manager, when I open properties for that public folder, I now get:
The mail proxy for this folder can not be found.  This may be due to replication delays.  The mail enabled pages will not be shown.

Sorry, probably should have mentioned this earlier, but during the migration, the user mailboxes moved over to the new Exchange server fine, however the public folders did not migrate over and I was forced to use the sledge-hammer approach and move them all to PSTs and recreate them.  Perhaps something w/ the replication issue?

Also...
When I now go to re-mail-enable the public folder that I removed from ADUC, I get the warming:

"You should only mail enable public folders if the public folder proxy was accidentally deleted.
If the public folder proxy is not accidentally deleted, check the confiugration of your AD Connector public folder connection agreement to ensure public folders are replicating properly from Exchange 5.5.

Do you still want to mail enable? Y / N

I re-mail-enabled that public folder and the addresses came up as needed.  I then added the "sales@domain.com" and it took just fine.
